  • Patent number: 11088381
    Abstract: A cell unit CU includes a cell structure 1, a metal support plate 2 disposed on one side surface of the cell structure 1, and a frame 3 holding an outer peripheral part of the support plate 2. The cell structure 1 has a lamination of an anode electrode layer 4, an electrolyte layer 5, and a cathode electrode layer 6, in this order. The frame 3 includes a displacement guide 7 at least on one side surface of the frame 3. The displacement guide 7 has a coefficient of thermal expansion that is different from that of the frame 3 and is configured to make the frame 3 curve so that the cell structure 1 is concaved in accompany with thermal expansion. In the cell unit CU, a risk of concentration of tensile stress on the electrolyte layer 5 at the time of thermal expansion during operation is removed without reducing the strength of the frame 3, whereby occurrence of a crack and the like in the electrolyte layer 5 can be prevented beforehand.

  • Patent number: 9233357
    Abstract: An exhaust gas purifying catalyst comprises: a plurality of catalyst units which contain anchor particles that support noble metal particles; and an enclosure material that internally contains the plurality of catalyst units and separates the catalyst units from each other. Both the anchor particles and the enclosure material contain an alkali element and/or an alkaline earth element. Due to this configuration, this exhaust gas purifying catalyst is capable of maintaining the exhaust gas purification performance by suppressing agglomeration of the noble metal particles even in cases where the ambient temperature is high.

  • Patent number: 8518846
    Abstract: In the present invention, slurry is formed by mixing noble metal-supported powder particles (3) and a binder (4) with each other in a liquid (Step S1), and the noble metal-supported powder particles (3) are dispersed by applying vibrations to the slurry (Step S2), and thereafter, the slurry is spray dried while keeping a state where the noble metal-supported powder particles (3) are dispersed (Step S3), whereby noble metal-supported powder (1) is produced. In the noble metal-supported powder (1) produced by such a method, pores through which exhaust gas flows are formed appropriately, and accordingly, exhaust gas purification performance can be enhanced.

  • Patent number: 7718567
    Abstract: An exhaust gas purging catalyst, includes: an integrated carrier; and a catalyst coat layer formed on the integrated carrier. The catalyst coat layer includes a catalyst component and meets the following expression (A): P?0.17W?0.04 - - - (A). P denotes a summation (ml) of a capacity of a void per mass (g) of the catalyst coat layer. The void has a pore diameter of 0.1 ?m to 1 ?m. W denotes a volume (ml) of the catalyst coat layer per the mass (g) of the catalyst coat layer.
